Migrate from bsddb3 to berkeleydb

[ZuesSSSSS]

Primarily converted the depreciated library bsddb3 to berkelydb

Added:

• Comments in the new, now named main.py file.
• Logging-to-file capability for the address and private-key. And to make it easier to copy the address/private-key

Updated:

• Linted the python files.
• Renamed some variables in main.py, to make the functions easier to understand.
• The output-ed Address-tuple was changed to a list to update into one long string, and to become easier to work with.

Your project literally made me super giddy and got me out of bed at 11pm to code until 2:35am
